In the context of climate change, it is important to look for alternative beef cattle fattening methods which could at least replace intensive cattle fattening. Fattening with grass forage could be useful, but not all beef cattle breeds are suitable for such type of fattening. The aim of this study was to compare Angus and Hereford purebred bulls’ fattening and slaughter results when grass forage was used for fattening. The results show that Angus bulls reached better fattening results in a shorter period. Average age before slaughter was 558±4.6 days with live weight 541.3±9.82 kg. They achieved highest live weight and carcass weight gain from birth to slaughter (904.7±20.76 g dE-1 and 506.9±13.80 g dE-1, respectively). Carcass conformation score in muscle development was higher for Angus bulls (2.8±0.10 points), but Hereford bulls showed slightly better fat score (2.2±0.08 points).
